This study is conducted in Japan of Freeze-dried Human Protein C Concentrate (TAK-662) used to treat participants with congenital protein C deficiency. The main aim of the study is to evaluate for adverse events and effectiveness of congenital protein C deficiency (TAK-662). During the study, participants with congenital protein C deficiency will be administered with TAK-662 intravenous injection in under routine normal practice. The investigators will evaluate adverse events due to TAK-662 for 12 months. For participants who will be administered in long-term supplementation of TAK-662 after acute treatment or short-term supplementation, the investigator will evaluate for 24 months as a maximum.
